I thought the series was the sum of An*cos(nw0t) + Bn*sen(nw0t)

Hi everyone, So I was trying to calcule the Fourier Series of x(t) = cos4t + sin8t, but I'm a little bit confused. What would be ω0 in this case since I have a combination of two functions with different frequencies? Thank you in advance.
